Three α/β compound nucleating agents based on 1,3,5-benzenetricarboxylic acid tris(cyclohexylamide) (BTA-99) were prepared by using β-nucleating agents aromatic diamides (TMB-5), dicarboxylic acid salts (CaPi) and rare earth compound (WBG-II), and nucleation effects of the nucleating agents in isotactic polypropylene (iPP) were investigated. The optimal ratio of BTA-99 to TMB-5, CaPi and WBG-II was 1:1, 4:1 and 2:3, respectively, and the crystallization peak temperatures of iPP nucleated with BTA-99/TMB-5, BTA-99/CaPi and BTA-99/WBG-II were ...
